IMPROVEMENT IN AUTOMATIC CAR-FANS.

Specification forming part of Letters Patent No. 187,033, dated February6, 1877; application filed June 19, 1876.

To all whom it may concern:

Be it known that I, JOHN B. MGNEILLE, of Philadelphia, Pennsylvania,have invented certain new and useful Improvements in Automatic Gar-Fans;and I do hereby declare the following to be a full, clear, and exactdescription of the same, reference being bad to the accompanyingdrawings, making part hereof.

My invention consists of the combination of a fan, a sleeve, a rod towork in said sleeve, and a crank upon an axle, substantially as and forthe purposes hereinafter described; also, of the combination of acompensating- -lever, formed by a sleeve and a rod, a crank to drivesaid lever, and a fan receiving its motion from the lever, allarrangedsubstantially as hereinafter set forth.

To enable others skilled in the art to make and use my invention, I willdescribe its construction and operation. i

In the drawings, Figure l is a side elevation of a car with my deviceattached thereto. Fig. 2 is a detached view, showing the arrangement ofthe belts.

A A are the car-wheels; B B, the shafts or axles of wheels A. U is acrank rigidly attached to axle B. D is a rod, pivoted at one end tocrank'G, the'other end of which rod rests and slides in sleeve E. SleeveE is rigidly attached to crank E, which, in turn, is rigidly attached toshaft G. This latter has dependent from it the oscillating fan H. J Kare pulleys on shaft I. M is a pulley on shaft L. P is a pulley on axleB, all connected by rubber belts N and 0. Fan R is dependent from shaftL, and is revolving.

As the wheel A revolves it turns the pulley P, and continuous motion istransmitted to belt 0, pulleys J K, belt N, pulley M, and this rotatesthe fan R. The ends of shafts L and G are supported by trunnions fromthe top of the car. The'motion of fan R sustains a cool circulation ofair in the car.

The fan H is set in motion as follows: Either by a bent axle, or bymeans of the crank G on the end of the axle, a motion is communicatedupward and downward, and to and fro, to the bar D, which slides insleeve E. This gives a swinging motion to sleeve E.

The sleeve E, being rigidly jointed to crank E, raises and lowers thiscrank, thus giving a partial revolution backward and forward to shaft Gand fan H.

The degree of the motion of fan H is regulated by the distance from theshaftv end of crank E at which E is jointed. If the end of sleeve E isjointed to crank E nearer to the shaft G, the motion is greater, as thesame lift is given by the sleeve to the point where it is attached as isgiven when it is attached to the end; consequently the rapidity anddegree of speed in the motion of the fan is increased. And the reverseis true as the point of juncture is moved away from contiguity to theshaft Gr. Thus, if the train to which the car is attached is to run at agreat speed-in other words, if it is for a steam-roadthe crank E islengthened, so as not to give too great speed to the fan, as the wheel Arevolves rapidly. If, on the contrary, the car is for a horse-road, thecrank E is shortened to give enough motion to the fan.

The two fans, acting in the same car, will produce opposite and variouscurrents, and keep the air in the interior of the car in a state ofhealthful action and coolness.

The belt 0 is of rubber, so as to give and take by its elasticity as thecar rises and falls on its springs; and the action of rod D in sleeve Eprovides for the same difficulty.

The lower end of rod D might be attached to the surface of wheel A.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination of fan H, sleeve E, rod D, and crank 0 upon axle B,substantially as and for the purposes described.

2. The combination ofa compensating-lever, E D, formed by sleeve E androd D, a crank, by which motion is imparted to the lever, and a fan, H,which receives its motion from the said lever, all arranged andoperating substantially as described.
